**Background**
Hematopoietic prostaglandin D synthase (H-PGDS) is a key enzyme responsible for the synthesis of prostaglandin D2 (PGD2) from PGH2. H-PGDS is primarily expressed in hematopoietic cells, such as mast cells and Th2 cells, as well as in the central nervous system. Due to its critical role in regulating inflammatory responses and various physiological processes, H-PGDS has become a significant target for pharmacological intervention in the treatment of allergic diseases and other inflammatory conditions. In recent years, the development of highly selective inhibitors has paved the way for more precise therapeutic strategies. In this context, we will introduce a selective H-PGDS inhibitor – TFC 007.
**Definition**
TFC 007 is a selective hematopoietic prostaglandin D synthase (H-PGDS) inhibitor with a high inhibitory activity, demonstrating an IC50 value of 83 nM.
**In Vitro Studies**
According to the TFC 007 description, this compound serves as a potent ligand for H-PGDS. Beyond its role as a traditional inhibitor, TFC 007 is utilized as a critical building block for the development of proteolysis-targeting chimeras (PROTACs). Specifically, it can be used to compose the H-PGDS degradation inducer (H-PGDS)-1, where TFC 007 binds to the H-PGDS target protein and pomalidomide binds to the E3 ubiquitin ligase cereblon, thereby triggering the ubiquitination and subsequent proteasomal degradation of H-PGDS. TFC 007 biological activity is characterized by its high selectivity and potency, making it an ideal tool for studying the functional consequences of H-PGDS depletion. For researchers requiring TFC 007 technical information, the compound possesses a molecular weight of 487.55 and a chemical formula of C27H29N5O4. In conclusion, TFC 007 is a selective H-PGDS inhibitor that provides a versatile platform for both enzyme inhibition and the development of targeted protein degradation strategies.
